To aZZ whom it may concern: I I

Be it known that I, JOSEPH BIJUR, a citi- Zen of the United States, and a resident of the borough of Manhattan, city, county, and. State of New York, have invented certain new and useful Improvements in Electric Regulators, of which the following is a specification accompanied by drawings.

This invention relates to electric regulators and systems of regulation; and the objects of the invention are to improve upon I the construction and operation ofsuehregulators and obtain a large range ofi'novement in the contact-controlling devices by means of a relatively small movement of an electroresponsive device, whereby regulation of the circuits may be more quickly and effectively produced than heretofore and the efficiency, sensitiveness, and certainty of operation of a system of electric regulation correspond- I ingly increased.

To these ends the invention consists of a regulator and system of regulation for carrying out the above objects embodying the features of construction, combinations of elements, and arrangement of circuits, coni nections, and parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in g which- Figure 1 is a diagrammatic representation, 1' partly in elevation, of apparatus and circuits embodying the invention. Fig, 2 is a detail perspective view of a portion of Fig. 1. Fig. 3 is a diagrammatic representation, partly in elevation, of another form of the invention.

The invention is shown in connection with l a system of electric distribution in which storage batteries are used in addition to the generating-dynamo, and an auxiliary dynamo is provided to cause the battery to charge or discharge as the external load decreases or increases. The voltage of the auxiliary dynamo is made to vary in direction and amount, or both, as the voltage requirements of the system may necessitate. The object i of such a system is to maintain a substan l tially constant load on the generating-dynamo, with a fluctuating external load, and my improved regulator is especiall efficient I in attaining the desired object, although, of i course, the regulator may be used with any i l I I l system or in any connection in which it may be found applicable.

Referring to all of the sheets of draw ings, A represents a suitable dynamo or source of supply connected to the mains b and 0, while the work portion of the system carrying the external load is represented by the conductors (Z and e. In this instance the load is represented by the lamps f by way of illustration Connected across the mains is shown a storage battery B, in series with which is arranged the armature of the auxiliary dynamo O, the field D of which is connected so as to be varied both in direction and amount by the electromagnetic controller which controls the resistances R and R, connected in circuit with the field-winding D of dynamo O The electric controller is so connected as to be responsive to changes in the external load of lamps f or other electroreceptive devices.

In each. of the figures two resistances'R and R are shown by way of illustration, in this instance connected in sections, as shown, to the individual segments S of the series of insulated segments Tand T. The resistances R and R are controlled by a contact moving along the contact-segments, and thus including more or less of the resistances in circuit. Definite points of contact between the contact-segments and the conducting are madeto travel along the series of segments, and the construction and operation of the apparatus is such that one resistance is included in the circuit as the other is cut out, and vice versa.

In all of the drawings the electric regulator is controlled by a suitable electroresponsive device, shown in this instance as an electroniagnet M included in the main line. The regulator made in accordance with this invention is constructed to multiply motion, so that a very slight movement of the magnet movement of the portions of the regulator which control the resistances It and R. The sensitiveness of the apparatus is thus very greatly increased, and a substantially con stant load on the generating-dynamo with a fluctuating external load is more readily obtained than heretofore, because a prompt response is given by the regulator when the load first begins to change In Fig. 1 suitable devices are shown operaii is shown connected to the lever G to op- I pose the attractive action of the magnet M. The arms P and P are suitably connected to the lever G, as by means of the screws Q and v V I v i V v insulated from said let ers by insulation Q As the core 0 movesup and down in accordance with the energization of magnet M it will be seen that one arm will be raised as the other is lowered. The series of segments T and T in this instance are shownangular in form. In the construction of the apparatus the points or edges 33 of the triangular portions otthe segments S are presented to the edges of the arms P and P, as illustrated in front view elevation in Fig. 1 and in perspec tive view in Fig. 2. The arms P P, as shown, move opposite the segments S, and since they are placed at an angle relatively to the. line of the segments it will be seen that a definite point of contact is formed between the segments and arms, which varies in accordance with the energization of the magnet M.

In the operation of the regulator any change in the load on the generator A will result in a change in the magnetization of the magnet M, which varies the resistance and produces a corresponding change in the vol tage of the auxiliary dynamo G. hen the load on the external circuit exceeds the normal, an excitation is given to the field D of dynamo C, which causes the dynamo to grain erate an electromot-ive force that adds itself to the electromotive force of the battery, causing the. battery to discharge and assist the generator. Conversely, when the external load falls below the normal an electromotive torce is produced in the auxiliary dyname (I in an opposite direct-ion, which assists the generator voltage to, send current into the battery. In orderthat the required variations of current may be produced in the field D, any suitable electrical connections may be provided, as shown, the. resistance R is connected across the line from the point 35 by wire 36 and from the point 37 by wire 38. T he resistance R is connected by wires 39 and L0 to points 41 and 42 on wires 36 and 38. The. field D of dynamo C is connected by wires 43 and A to the arms P and P, respectively. \Vhen the arms P and P each hear u on the. central se ments of the series T and T, there will be no dill'crencc of pott n tial between them, because through the. resistance R is equal to that through resistance R, and there will be no ditl'erence of potential between the middle portions of the series ot contacts T and T.

the voltage drop ments, there will be various values of electro I motive force between the arms in one direc tion or the other, by means of which con struction and operation the excitation of the i field D, and consequently the voltage of the l armature of the auxiliary dynamo G, will l vary in position and amount with the movet I ment of the arms P and P respectively, to l the angular segments S. When the apparatus is in the position shown in Fig. 1, in which both arms P and P i make contact with the inner segments of the series T and T, it will be seen that the arm P is at the same potential as the positive side of the system, and the arm P will have the potential of the negative side. There will i therefore be between these two arms the full voltage of the source of exciting-current for l the field D, the current passing from the point 35 by wire 36 to arm P, thence by wire 43 to and through the field D, back by wire 42 to arm P, thence by wires 40 and 38 to the point 37 on the negative side of the system. When the lever G is tilted and the 1 position of the arms P and. P is reversed, the full line potential will be impressed upon the l field D, but inthe opposite direction. \Vhen l both arms P and P make contact with the outer segments of the series T and T, it will be seen that the arm P will be. at the potential of the negative side of the. system, while arm P will be at the potential of the positive side. Therefore current will flow from the. point 35 on the positive side of the system by wires 36 and 39 to arm P, thence by wire 414: through field D and back by wire 43 to arm P, and thence by wire 38 to the point 37 on the negative side of the system, thereby reversing the current in the field I). It is l obvious, therefore, that the booster-field D l may be varied in strength from zero to a maximum in either direction and that. any.

desired number of intermediate field strengths may be obtained by varying the resistances R and R inversely to each other.

In Fig. 3 the series of taintact-segments T and T are made fiat, and curved conductingarms P and P, as shown, are adapted to roll upon the segments, thereby forming a rolling contact between the arms and the segments, which moves along the length of the segments from one end to the other. In this manner the resistances lt and R are varied.

Any suitable means may be provided conl nected to operate the rolling arms P and P. l Suitable means are shown in Fig. 3, which in I this instance consist of the T-shapcd lever i, l connected to the arm K of core ol' magnet i .\l atone end and provided with a r(- tracting i spring L at the other end. The lever i. is pivoted at ll to a support I and is provided with l a downwardlydepending arm j, to which a rod 7c is pivoted at one end. To the other end of the rod is is pivoted the curved arm P also a rod Z. To this latter rod Z is pivoted the curved arm 1. The circuits and connections of Fig. 3 are substantially like those of Fig. 1, so that the description of the operation oi Fig. 1 applies to Fig. 3. As the energization of magnet M varies it will be seen that the rolling-arms P and P will be rocked and the point of contact between said arms and the segments T Z and T will travel from one end of the segments to the other, according to the movements of the core 0 of the magnet M. Both arms P and 1 make contact at the left-hand ends of segments T and T at the same time or at the left-hand ends at the same time.

\Vith the parts in the position shown in Fig. 3 the contact-arm P will be at the potential of the positive side of the system and contact-arm P will be at the potential of the negative side. Current will therefore flow from the point by wires 36 and 39 to the arm P, thence by wire 44 to and through the field D, back by wire $3 to arm P thence by wire 38 to the point 37 on the negative side of the system. When the arms P and P are rolled along the contacts until they make contact with the segments at the righthand ends of the series, it will then be seen that contact-arm P will be at the potential of the positive side of the system and arm P will be at that of the negative side. Then current will flow from the point 35 by wire 36 to arm P thence by wire 43 through field D, back by wire -14 to arm P thence by wires and 38 to the negative side of the system to the point 37. When the contact-arms P and 1? rest at the middle port-ions of the series of segments T and T there will then be no diiierencc of potential between said arms, and there will be no current in the field D. The current in the field D is thus varied in direction and amount, according to the needs of the system.

Although the series of contactsegments T T are shown flat in Fig. 3 they may be either flat or curved, the only limitation being that the curvature of the surface of the segments should di'iier materially from that of the rolling arms.

Obviously may be used ti'on may be forms.
